Discord.py：如何从 UserID 获取用户？

Question

So I need my bot to get a user from a UserID. I tried it like this:

import discord
from discord.ext import commands
from discord.utils import get

client = commands.Bot(command_prefix = '&')

@client.command(pass_context = True)
async def test(ctx, id : int):
  user = client.get_user(id)
  print(user)

TOKEN = ""
client.run(TOKEN)

but it always returns None, but why? :C Thanks for helping.

Answer 1

async def test(id: int):
    user = client.get_user(id)

    if user is None: # Maybe the user isn't cached?
        user = await client.fetch_user(id) 

    return user

# Inside the loop
user = await test(12312312313)

Also remember to enable intents.members , here's how

Depending on what you're trying to do you're probably missing intents.

import discord
from discord.ext import commands

intents = discord.Intents.default()
intents.members = True

bot = commands.Bot(command_prefix='&', intents=intents)  # renamed bot because you're using an instance of Bot



@bot.command()  # pass_context is not necesary since more than few versions back
async def test(ctx, user_id):  # renamed id to user_id to make it more readable
  user = bot.get_user(user_id)
  print(user)

TOKEN = ""
bot.run(TOKEN)

Take into consideration the code above retreives a "user" object not a "member". The distinction is important if your leaderboard is related to a specific server. Also, the user object doen't have attributes such as "roles", "nickname", etc. If you wish to retreive that information you need to get a member object using ctx.guild.get_member instead of bot.get_user
